Metabolic enzyme activities in black bream (Acanthopagrus butcheri) from the Swan-Canning Estuary, Western Australia

The CCO and LDH activities in liver, white muscle and gill tissues in the black bream (Acanthopagrus butcheri) were measured to determine their aerobic and anaerobic metabolism. Black bream were collected from five sites within the Swan-Canning estuary under summer conditions in 2001 and 2002 and again under winter conditions in 2002. Enzyme activity levels in the tissues taken were compared to identify spatial, seasonal or\nannual variations.

本研究测定了黑鲷（Acanthopagrus butcheri）肝脏、白肌及鳃组织中的细胞色素c氧化酶 (Cytochrome c Oxidase, CCO) 与乳酸脱氢酶 (Lactate Dehydrogenase, LDH) 活性，以明确其有氧代谢与无氧代谢水平。研究样本于2001年、2002年夏季以及2002年冬季，采自天鹅-坎宁河口（Swan-Canning estuary）的5个采样点位。对所采集的组织样本的酶活性水平进行对比分析，以识别其空间、季节及年度差异。
